Release 1.1.1

1.1.0 版本提交的代码出现了点小错误，如使用了上一版本代码的请立即更新此版本，抱歉。

Features

• Batch propose.
• Learn faster.
• bugfix.

此版本带来了一个新的特性，提供一个批量提交接口，但是形式上和单次提交接口一致，由内部自动完成批量逻辑，从而大幅降低写盘次数以及网络通信次数，提高吞吐。该接口已在微信生产环境稳定执行超过万亿次。

修复了一个重大BUG，某些编译环境下会导致单调时间获取不正确，从而使得设置了CLOCK_MONOTONIC的condition工作不正常，表现为运行卡死，Master无法选举等。如出现类似现象的，建议立即更新此版本。
